AUTOMATIC LUB'RICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No, 237,800, dated February 15, 1881.

Application tiled October 15, 1880.

To all whom t may concern: l

Be it known that I, GEORGE W. BAKER, of

Chicago, in the county of Cook and State ot" ing to be a full, clear, and exact description of the invention, that will enable others skilled in the artto which it appertains to construct and make use of the saine, reference being had to the accompanyin g drawings, and to the letters and iigures of reference marked thereon, forming a part ot' this specification.

This invention relates to that cla-ss of lubricators which are employed to lubricate the interior working parts of a steam-en gine, and is adapted to be used in connection with all classes of steam-engines, the operative functions bein g .hydrostatic pressure, the exact construction and operation of which will be hereinafter more fully set forth in detail.

Figure 1 is a side elevation, in perspective, of my lubricating apparatus. Fig. 2 is a vertical section ot' the same, and Fig. 3 is a detached detail of construction.

Referring to the drawings, A represents a transparent oil-receptacle, cylindrical in form, the ends being closed by means ofthe metallic ianged ends ay ce, which are secured in position relative to the receptacle A by the clampin g-bolts ce et', the general construction of the oil-receptacle being the same as that already described in connection with former patents issued to me.

The condensing-chamber B receives the steam for condensation from the steam-pipe C through the pipe D, and the water from the conde-asin geharnber passes down through the vertical stand-pipe et into the horizontal part or connection 5, from thence into the drop-pipe 6, arranged on the interior of the oil-receptacle A, and discharged into the lower end of the oil-receptacle. The lower open end of the droppipe 6 extends down into and is inclosed by the open vertical tube 7, which serves to trap a portion of the Water in the oil-receptacle for the purpose of preventing the oil passing into the passage leading to the condensing-chamber, as shown in Fig. 2 of the drawings. The oilpasses from the receptacle (No model.)

A up through the transparent tube 8, into the horizontal part 9, drops down through Jthe vertical connection l0, and passes into the horizontal pipe l1, which has the open or discharge end inserted in the steam-pipe C turned down, as shown in Fig. 2 ofthe drawings, so as to discharge the oil into the steam at a point below the steam-passage communicating with the condensi[1g-chamber, thereby preventing any portion otthe oil passing with the steam into the condensing-chamber. The pipe 11 is somewhat smaller in diameter than the passage inclosin g the same, which form ot' construction permits of a free passage for the steam to the condensing-chamber around the pipe 11, and requires but one connection to be made in order to attach the lnbricator to the steam-pipe, as shown in the drawings.

Between the oil-receptacle A and the transparent tube 8 is placed the tapering nozzle l2, the upper end ot' which extends tar enough into the glass tube S to show plainly the drop of oil forming on the end ot' the same. The drop of oil, when it has grown to a certain size, breaks away and passes upward into the oilpassage leading to the steam-pipe or other point to which the lubricator may be attached. This tapering nozzle is of the form shown in Fig. 3 of the drawings. The interior passage. for the oil is not contracted as it approaches the upper end ot' the nozzle, but is ot' the same size the entire length of the nozzle, the outer dimensions of the nozzle being reduced on a straight line, instead of being oval or rounding near the end. rEhe upper end of the nozzle is not drawn to a thin or sharp edge, but sufcient material is left to provide a seating capacity for the drop of oil to rest on while forming.

Practical working has proven that a nozzle that is oval on the tapering end and reduced toa thin or sharp edge gives no seating area for the drop of oil, and a portion4 ot' the oil will adhere to and pass down the outside ofthe nozzle and be caused to break away in small The form of nozzle herein shown and described is found to obviate this evil, and prevents any ot' the oil from reaching the glass tube.

The ball-valve 13, placed in the oil-passage between the oil-receptacle and the lower end ot' the nozzle, prevents the water in the glass tube 8 from escaping.

The globe-valve 14E closes the passage between the oil-receptacle and the condensingchamber, andthe globe-valve l5 closes the oilpassage, these valves serving to regulate and control the operations o1 the apparatus.

The part 5 is formed of one piece, and has connections with the steam, water, and oil passages. The ball-valve 16, placed in the oilpassage, is back-seated by the pressure ofthe steam when the lubricator is in operation; but when the throttle-valve ot' the engine is closed the luxll-valve gravitates to its seat, completely closing the passage and preventing the vacuum formed in the steam chestand cylinder ot the engine from having an ei't'ect on the lubricator or drawing the water out ot' the glass tube S.

The ball-valve 17, placed in the passage leading` from the steam-pipe to the condensingchamber, closes the passage in the same manner, and prevents a vacuum from ai'i'eeting the condenser. These ball-valves lnovein a cage, and when back-seated lodge against a shoulder, which prevents the passage from being closed by the valve when it is i'orced back outot' its seat proper, the general construction aml operation being the same as that shown and described in t'ormer patents issued to me.

After the lubricator is attached to the engine the oil-receptacle should be slowly tilled with water from the condeusiiigclianlber and allowed to pass up into and till the glass tube 8'. \Vhen this is accomplished the wastevalve 1S should be opened, when the 'ater in the oil-receptacle will run out on a level with the vertical tube 7, the water in the glass tube S being retained there by the ball\ alvc 13. The receptacle may now be tilled with oil by removing the screw-cap 1S), which will open a passage communicating with the interior ot' the oil-receptacle. The valve let, controlling the water-column from the condenser, should now be opened a little, and as the water is discharged into the bottom ot" the receptacle the oil is fed out through the top ofthe same and drops ott' from the end ot' the nozzle 12, and passes up through the water in the glass tube 8, as shown in Fig. 1 ot' the drawings, and passes on until discharged into and mingled with the steam to be lubricated.

By means ofthe globe-valves 14 and 15 the operation of the apparatus is regulated to feed slow or fast, as may be required, and they need not be closed each time the engine is stopped, the ball-valves automatically opening and closing the oil and water passage.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a lubricatingapparatus, the combination, with the central part, 5, ofthe ball-valve 16, and an oil-conducting pipe consisting of the vertical part. 1t) and the horizontal part 9, substantially as herein shown and described.

2. In a lubricating al'iparatus, the combination, with the transparent oil-receptacle A, ot' the supporting part 5, having a single 'passage through the interior thereof, as described, of the stand-pipe 4, the comlensing-chamber B, and the pipe D, substantially as and for the purpose set forth.

3. In a lubricatingapparatus, the combination, with the. transparent oil-receptacle A, ot' the ball-valve 13, the tapering nozzle 12, the glass tube 8, the globe-valve 15, the oil-conducting pipe consisting ot' the parts 9 and 10, the ball-valve v16, the main supporting part 5, and the horizontal pipe 11, substantially as herein shown and described.

4. A lubricating apparatus adapted to be automaticallyv operated by means ot' a hydrostatic column or pressure, consisting, essentially, ot' a transparent oil-receptacle having a trapping device arranged on the interior thereof, for the purpose ot' retaining a portion ot' the product ot' condensation therein, and having proper communication with a condensingchamber, connected with a central supporting part', provided with a single cored passage through the interior thereof, said passage inclosing an oilconducting pipe ot' a somewhat smaller diameter, whereby steam i'or condensation and the oil t'or lubricating purposes are received and discharged through one and the same opening inte the steam pipe or other part to which the apparatus may be attached, said oil and steam passages being closed by a system ot' ballvalves adapted to be backseated by the pressure ot' steam when the lubricator is in operation, and automatically closed by the combined action ofthe vacuum andthe force ot' gravity when the stl-am is sluit oit, for the purpose ot' preventing the vacuum t'ormed in the steam chest and cylinder i'roiu acting on the lubricator when the engine is running dry, all constructed and arranged to operate as herein described.
